Might not look cool, but if the iPhone dock was on the top part of the body (on the thin surface, rather than on the body surface), then you would be able to look at the iPhone as you're playing. Currently, you can either look at the strings or on the iPhone, where you almost have to look backwards to look at the iPhone. As a beginner guitar player, learning would be easier if I could see the tabs and my strings at the same time. my 2c.

It just looks like it should be at the top rather than the bottom. With this setup you always have to look over your hand to see the iphone screen.

But why would you be looking at the iPhone screen other than when interacting with it using said hand?
